Not working, power is on but nothing is coming up in the screen

Some kind of feedback perhaps? Are you using a multi core with sends & receive inside it but NOT individually screened? i.e. "pick up" inside the cable? Is it both speakers? Try them one at a time in case one is faulty but affecting the other? Unplug the input leads & see if the speakers by themselves are making any sound ( a small hiss?) If the speakers with no input (but powered :-) makes no whistle then it's coming from other gear...... Also the speakers may have switch mode power supplies & if you don't have a decent ground you could have problems. Make sure you have a good ground connection back to the fuse board. If you studio is in a shack at the end of the garden running on extension cords you may need a local connection to ground..... Good Luck!

The outputs of these mixer needs to be connected to an active speaker.

An active speaker have an amplifier and a preamplifier.

You will have to assign the i/o setting in your DAW's prefrences.

If you hook it up with the USB cable Logic should recognise it. You may have to select it in the Audio Preferences as your Audio Interface.

what program are you running and did you set up your keyboard with the software so it can recognize it. Depending on what software it is your using as soon as I know I can tell you how to get it working. I use my midi keyboard with everything from reason, Ableton live, pro tools logic logic express vdj traktor basically every software!

SEE IF IT IN DEVICE PRINTER AND RIGHT CLICK AND TROUBLE SHOOT.

The AXIOM SHOULD turn on with just the wall wart adapter so you HAVE A PROBLEM.

First thing is to check the adapter that it is the correct one. It should be a 12 VDC 1 amp unit with positive center pin output.

Common adapters for pedals WILL NOT WORK.

Assuming you have the correct adapter, VERIFY the connector is plugged fully in the AXIOM.

What are you going to hook up to?

Essentially you connect the power cord to power and connect outputs from say a mixer to the inputs using TRS balanced cables... and connect the outputs of the unit to your power amplifier.

Note taht there are MANY other possibilities using "inserts:on some devices.

I would suspect a setup problem. Your best bet would be to contact Rolan Customer Service. /here's their link-
